“Tomorrow against BorussiaMonchengladbach we’ll see the same Lazio we admired up until a few days ago,” assured the Coach.

They welcome Gladbach to the StadioOlimpico for the second leg of their Europa League Round of 32 tie, which kicks off at 18.00 GMT.

“Usually German teams believe in qualification right to the end, until the referee blows the final whistle. Therefore the 3-3 is by no means a result we can rest on.

“I want a concentrated Lazio, aware of its own strengths and eager to prove itself on home turf. Blackouts can happen during the course of a campaign. We need more consistency and a clinical edge, just as Siena had with us.”

Michael Ciani was disastrous against Siena, as was the three-man defence, but Petkovic laughed off criticism.

“Is it wrong to have three at the back? I guess that means we’ll practice using two instead... The truth is every game has its story and we must face this one with the utmost effort to win.

“Recently we have conceded too many goals due to individual errors, which means we need more concentration and discipline.

“I expect Borussia to play more or less the same way they did in the first leg, a referee that won’t be affected by the atmosphere and the crowd that will be cheering us on.”

Stefano Mauri and Ederson remain major doubts to feature, while Andre Dias is suspended after his red card in Germany for giving away two penalties.
